21.3: A New Patterning Method for Full‐Color Polymer Light‐Emitting Devices: Laser Induced Thermal Imaging (LITI)

Abstract

Abstract We have developed a new color patterning method for the patterning of full color polymer light‐emitting devices. Laser Induced Thermal Imaging (LITI) involves the imagewise exposure of a thermal transfer film with a scanning near infrared laser. During the process, light emitting polymer (LEP) is transferred from a thermal film to a circuitized substrate. Using the technology, we fabricated a 3.6″ QVGA full color active matrix polymer light‐emitting device (PLED).
